Watch Nik Wallenda tightrope walk between Marina Towers in Chicago

Daredevil Nik Wallenda successfully walked between Chicago skyscrapers on Sunday night without a safety net. In one part of the walk, Wallenda walked on an incline, and the other part he did while blindfolded at over 600 feet into the air. The stunt was aired on LIVE TV (with a 10 second delay) in case Wallenda fell off of the tightrope.
